gianfar: Don't needlessly set the wrap bit for the last RX BD

startup_gfar() sets the wrap bit for the last rxbd just after
gfar_new_rxbdp() call, which is issued for all rxbds. And
gfar_new_rxbdp() has the following check already:

if (bdp == priv->rx_bd_base + priv->rx_ring_size - 1)
lstatus |= BD_LFLAG(RXBD_WRAP);

So we don't need to set the bit again.
